Title: Fibre-reinforced polyurethane materials
IPC: C08L75/08
Filed: 1967-04-03
Abstract: 1,139,114. Glass cloth laminates; glass fibre reinforced polyurethane articles. ALLIED CHEMICAL CORP. 3 April, 1967 [5 April, 1966], No. 15201/67. Headings B5A and B5N. [Also in Divisions C3 and F2] Glass cloth discs may be laminated by impregnating such discs with a polyurethane resin mix comprising (a) a blend of polyethers having an average functionality of 3À75 to 7À5 and an average hydroxyl number of 300 to 600, and obtained either (1) by reacting one or more alkylene oxides with a mixture of polyhydric alcohols containing 2 to 8 hydroxyl groups or (2) by mixing at least two different preformed polyethers each obtained by reacting at least one alkylene oxide with a polyhydric alcohol containing 2 to 8 hydroxyl groups and (b) an organic polyisocyanate, the NCO: OH ratio being between 0À8: 1 and 1À3: 1, and bonding the discs together by heat and pressure. In an Example (XII), the polyether is one prepared by propoxylating a 30: 70 (equivalent ratio) glycerol/sucrose mixture and the polyisocyanate is a mixture of isomers of tolylene diisocyanate. The laminate after being removed from the mould is post-cured by heating. Filament wound polyurethane structures may be prepared by coating continuous glass filaments with a polyurethane resin prepared as indicated above, winding the resulting impregnated filament under tension on a winding machine or mandrel and heating the wound structure to cure the resin. In an Example (XI), glass roving was fed from spools to a comb and into a resin bath containing a polyurethane derived from a propoxylated glycerol/sucrose mixture and tolylene diisocyanate. Excess resin was removed by passing the roving between rollers and it was then passed through a guiding eye on to a mandrel where it was wound and the resin cured in a press at elevated temperature.

Abstract: 273,272. Costello Engineering Co., (Assignees of Costello, T. J.). June 25, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Changing; doors.-Bars or billets such as are used in the manufacture of sheet metal are fed to and advance through a furnace in an inclined position. The furnace has a side fire-place at the charging end and a rail track 3 for the billets, beneath which is an open-topped flue 5 in communication with the space above the line of billets A by an end opening 6. The billets form a cover for the flue 5, and they are maintained in a slightly inclined position by a pivoted catch 12 on the door 9. The forward face of the pusher head 7 is inclined at the angle at which it is desired to maintain the billets, and the catch 12 is so shaped that it is lifted as the billets are fed into the furnace, and drops by gravity behind them. A portion of the heating-gases passes between the billets owing to the burrs formed thereon in the shearing operation.

Title: Improvements in and relating to weighing machines
IPC: G01G13/00
Filed: 1936-06-08
Abstract: 476,389. Automatic-feed weighers. SIMON, W. G., and SIMON, F. R. June 8, 1936, No. 15941. [Class 143] Relates to an automatic weighing- machine of the type comprising a supply hopper, a weigh pan, a feed gate, a spring for opening the feed gate, means whereby upward movement of the weigh pan stresses the spring preparatory to opening the gate and means for releasing the gate for opening movement by the spring. According to the invention a spring other than a compression spring (preferably a tension spring) is used for moving the feed gate thereby obviating disadvantages due to clogging of the spring. As described in Specification 476,388, the weigh pan 13 in rising after discharging its contents rotates a three-armed lever 20a, 20b, 20c. The arm 20b is connected by a tension spring 22 to the feed gate 11, and the tension spring is consequently extended to bias the gate towards the open position, and subsequently to open the feed gate when a toggle joint 39, 40 is broken by the closure of the discharge valve of the scale pan. As the scale pan descends, followed by the threearmed lever, the tension of the spring is relaxed sufficiently to allow the feed gate to descend by gravity to the dribble feed position, final cut-off of the feed being subsequently effected as described in the above-mentioned Specification.

Abstract: 921,311. Radar. GENERAL ELECTRIC CO. May 5, 1961, No. 16408/61. Class 40 (7). In pulse radar apparatus which includes pulse expansion in the transmitting channel and pulse compression in the receiving channel, one network is utilized to carry out both functions. In one embodiment the network is shown in block 12<SP>IV</SP>, Fig. 6; block 11<SP>1</SP> provides a source of modulated pulses, and comprises a pulse repetition frequency generator 50, Fig. 7a, which may be crystal-controlled, a pulse delay circuit 51, Fig. 7b, producing a delay equal to the total time delay in network 12<SP>IV</SP>, a monostable multivibrator 52, Fig. 7c, an amplitude modulator 53, Fig. 7d, a transmitter timing pulse generator 55, Fig. 7e, and a receiver gating pulse generator 56, Fig. 7f. The receiver gating " on " pulse is sufficiently long to prevent connection of the receiver to the expansion-compression filter 12<SP>IV</SP> during periods of transmission and to disconnect the receiver therefrom in advance of transmission by a time equal to the delay in the filter. Timing of type A display 21 is effected via delay 22. The transmitting channel components include a frequency converter 57, an oscillator 58, the filter 12<SP>IV</SP>, a second frequency converter 59, a radio-frequency source 60, a klystron power amplifier 61 and a modulator 62. The output pulse R.F. component from converter 57 is at 1 Mc/s. The receiving channel includes an I.F. amplifier centred on 9.945 Mc/s., receiver gate 67, frequency inverting converter 68 and an associated oscillator 69 running at 10.89 Mc/s. The expansion-compression filter incorporates amplifiers 71, 75 ..., time-delay lines 73, 78 ... each producing a delay of 4.75 microseconds, balanced modulators 72, 76 ... and filters 74, 77 ... ; the amplifiers are adjusted to restore the insertion losses of preceding units. A circuit diagram of one stage of filter 12<SP>IV</SP>, omitting the delay line, is illustrated in Fig. 8. First valve 101 is an amplifier with an input volumecontrol 106, beam modulator valve 102 is in the balanced modulator section, and valves 103, 104 afford amplification and isolation in the output band-pass filter. Balanced modulator gain is adjustable by means of potentiometer 118, and the distribution of carrier voltage between electrodes 113, 114 is balanced by means of potentiometer 116 to obtain complete carrier suppression in the modulator output. Simpler embodiments of the invention are described, Figs. 4, 5 (neither shown). The invention may be used in systems where carrier frequency shifts between transmitted and received pulses are utilized, the pulse detector then being a synchronous detector supplied by the initial pulse carrier.
